Slope finishing abruptly about civileng HOT 3 CLOSED

Same issue is had with the Earthworks tool (tried with a full-slope earthwork) :

{ 'DEM' : 'XXXX/Test-MDT-Migas.tif', 'cut_slope' : 1, 'fill_slope' : 3, 'new_DEM' : 'TEMPORARY_OUTPUT', 'platform' : 'C:/Users/RVV/Desktop/Platform.shp', 'platform_level' : 400 }

from civileng.

When the Reservoir tool is used, slope stars correctly from poliline marked and starts the slope at selected ratio (1:H). But suddenly, when slope reaches 100 meters each side in plan view, it descends abruptly to the terrain. I tried in several locations obtaining the same result. Lake is obtained correctly.

Two figures are attatched to ilustrate the problem.

INPUT: ({ 'DEM' : 'XXXX/Test-MDT-Migas.tif', 'dam_top_level' : 400, 'dam_vector_layer' : 'C:/Users/RVV/Desktop/Test-LIN.shp', 'dam_wall_slope' : 3, 'new_DEM_raster' : 'TEMPORARY_OUTPUT', 'new_lake_raster' : 'TEMPORARY_OUTPUT', 'reservoir_inner_point' : '576415.550627,4132294.982787 [EPSG:3042]', 'water_depth_from_top' : 5 })

Hi there,

This particular issue can be solved editing the file "Reservoir_algorithm.py" in the Qgis plugin folder located under your Qgis profile directory (you can open it directly from Qgis) and changing the line 'RINGS': 1000, to 'RINGS': 10000,

Try it and please come back to me if it doesn't solve your problem.
